What is the "yam-yam"?
This is the episode when Elaine goes to an office dinner and makes out with this guy called Zach on the dinner table after having one too many? She told everybody they were dating to avoid being the office skank. When Peterman told her to help him through his cold turkey, she told Peterman about him making out with another woman in the office building and thus she would like to break it off. Peterman then said, "That's not Zack, that was the yam-yam".
